Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.

MRI of the orbits with contrast demonstrates a well-circumscribed rounded mass located in the superior medial quadrant in the extraconal space. The mass is intermediate in T1 signal and high signal on T2 weighted images. Contrast-enhanced sequences demonstrate gradual and complete enhancement.

The last obtained sequence is the non-fat suppressed axial T1 image (image 4) also demonstrates a lovely chemical shift artifact at the edges between the mass and the orbital fat.

Features are characteristic of an orbital hemangioma.
